I've used Nero Recode 2 (I'm not using the latest version) to convert a DVD to mp4 format. I want it to fit on 2 CD-Rs. Is there a way of splitting these mp4 files into 2 700meg files with adjusting the settings in Nero. Or any other 3rd party software that will split mp4 in any size that I specify? And if there is more than one track on a DVD, how do I join the mp4 files created by Recode?
